AI Technical Summary

Benefits of technology

The invention is a bearing that overcomes disadvantages of previous designs by being easy to make and handle at a low cost, even at large diameters. It is a rotational guide with segmented tracks for milling elements, such as rolls or balls, that automatically align themselves during assembly. The bearing also has a sealing effect to protect the track elements from environmental influences. The advantage of this bearing design is that it allows for greater manufacturing tolerances at large diameters, making it easier to fabricate and machine. It can also be used in a straight design for applications that do not require an annular shape.

Problems solved by technology

Despite their size, they are fabricated with great precision, which results in correspondingly high costs.
In addition, the one-part tracks of the bearing elements are very hard to handle.

Embodiment Construction

[0027]FIG. 2 illustrates consoles 8 of carriers 9 in a round kiln (not explicitly shown) at a malting facility with an interior tower accommodate an annular rotational guide for a screw stripper or loader / unloader. The rotational guide (interior guide) can here have a diameter of approx. 12-20 m, wherein a segmented design is possible starting at a diameter of approx. 3 m.

[0028]The rotational guide comprises of several segments (in this case 24) interconnected by connecting and centering elements 4, wherein each segment comprises of an upper segment 1 and lower segment 2. The upper and lower segments 1, 2 have tracks with running surfaces 6 and 7, between which roller balls 3 move. The running surfaces 7 are only milled, which is sufficiently precise for slow running, and reduces the manufacturing costs.

[0029]In addition, the upper and lower segments 1, 2 are designed in such a way that a seal 5 is formed, securing the roller balls 3 and running surfaces 6, 7 against contaminants. T...

Abstract

The invention relates to a bearing assembly, which includes at least one upper segment with an upper running surface and at least one lower segment with a lower running surface. The bearing assembly also includes at least one roll element movably arranged between the upper running surface and the lower running surface.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a U.S. National Stage of International Patent Application No. PCT / CH2005 / 000668 filed Nov. 11, 2005, and claims priority of German Patent Application No. 10 2004 057 676.9 filed Nov. 29, 2004.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a bearing and, in particular, to an annular bearing or internal guide for executing planar rotational movements, e.g., in round drying kilns, furnaces, or flat-bottom distributing guides.[0004]2. Discussion of Background Information[0005]Ball or roller bearings with a large diameter for executing planar rotational movements are known in the art, e.g., for slewing cranes, tanks, or machine tools. Despite their size, they are fabricated with great precision, which results in correspondingly high costs. In addition, the one-part tracks of the bearing elements are very hard to handle.SUMMARY OF THE INVENTION[0006]An aspect of the invention ...
